Description

PET 더스트 배출 시스템이 구비된 사출 금형Injection mold with PET dust discharge system
본 발명은 PET 더스트 배출 시스템이 구비된 사출 금형에 관한 것이다. 더욱 상세하게는 PET 재질의 수지 더스트가 피스톤이 작동하는 공간에 퇴적되면서 피스톤의 동작 효율을 저하시고 게이트 실링을 방해는 문제가 발생하여, 제품 생산의 계획에 대한 차질이 발생하는 것을 미연에 방지할 수 있도록 매니폴드 내부에서 핀가이드 부시와 밸브핀 사이로 누출된 PET 더스트를 외부로 방출시키는 배출 장치가 구비된 사출 금형에 관한 것이다.The present invention relates to an injection mold equipped with a PET dust discharge system. More specifically, PET resin resin dust is deposited in the space where the piston operates, which lowers the operation efficiency of the piston and hinders the gate sealing, thereby preventing the disruption of the production plan. It relates to an injection mold having a discharge device for discharging the PET dust leaked between the pin guide bush and the valve pin to the outside so that the inside of the manifold.
사출금형장치의 경우, 사출시 공급되는 용융수지가 매니폴더의 런너나 노즐의 수지통로를 통과할 때, 런너와 노즐의 수지통로의 내벽을 따라 유동하는 수지는 내벽과의 마찰저항 때문에 중앙부분을 통과하는 수지에 비하여 상대적으로 느리게 유동한다.In the case of the injection mold apparatus, when the molten resin supplied during injection passes through the resin passage of the runner or nozzle of the manifold, the resin flowing along the inner wall of the resin passage of the runner and the nozzle is separated from the center part due to the friction resistance between the inner wall. It flows relatively slowly compared to the resin passing through.
이러한 사출금형장치의 매니폴더의 런너 내의 수지흐름 특성으로 인하여, 사출성형을 일시 정지하거나 종료하고 나면, 런너의 내벽이나 노즐의 수지통로의 내벽에 수지가 잔류하게 된다. 더구나, 매니폴더의 런너의 길이가 긴 경우, 런너 내벽과의 유동마찰 저항이 증가하여 런너 내에 잔존하는 수지의 량은 증가하게 된다.Due to the resin flow characteristics in the runner of the manifold of the injection molding apparatus, after the injection molding is paused or terminated, the resin remains on the inner wall of the runner or on the inner wall of the resin passage of the nozzle. In addition, when the length of the runner of the manifold is long, the flow frictional resistance with the inner wall of the runner increases, so that the amount of resin remaining in the runner increases.
이와 같이 런너나 노즐의 수지통로 내벽에 잔류하는 수지는 히터의 열에 의해 탄화되어 변색되고, 뿐만아니라 수지(특히, 색상이 다른 수지)를 교체하여 사출성형을 할 때, 새로운 수지에 혼입되어 성형불량을 발생시킨다.In this way, the resin remaining on the inner wall of the resin passage of the runner or nozzle is carbonized and discolored by the heat of the heater. In addition, when the resin (particularly, a resin having a different color) is replaced, the resin is mixed with a new resin to cause poor molding Generates.
따라서, 종래 사출금형장치에서는 런너 내벽 또는 노즐의 수지통로 내벽에 잔류하는 수지를 완전히 배출시켜 제거할 때까지 새로운 수지를 공급하여야 하므로수지 교체에 따른 수지의 소모량이 많아 지는 단점이 있었다.Therefore, the conventional injection mold apparatus has a disadvantage in that the consumption of the resin is increased according to the resin replacement because the new resin must be supplied until the resin remaining on the inner wall of the runner or the resin passage of the nozzle is completely discharged and removed.
한편, 사출금형장치로 용융수지를 공급하는 용융수지공급장치는 정해진 용량의 수지를 용융하여 사출하기 때문에 금형 내부의 캐비티로 공급하는 용융수지 공급용량이 정해져 있다. 이러한 수지공급장치의 공급용량에 비하여 금형내에 마련된 캐비티의 용량이 상대적으로 적은 경우, 매니폴더의 런너 내부에 잔류하는 잔류 수지의 량도 증가하므로 다른 이종의 수지로 교체하여 사출할 때 제거하여야 할 수지 소모량도 그만큼 증가하는 문제점이 있다.On the other hand, the molten resin supplying device for supplying the molten resin to the injection molding apparatus melt-injected a resin of a predetermined capacity, so that the molten resin supply capacity for supplying to the cavity inside the mold is determined. When the capacity of the cavity provided in the mold is relatively small compared to the supply capacity of the resin supply device, the amount of residual resin remaining in the runner of the manifold also increases, so that the resin to be removed when exchanging with another resin is injected. There is also a problem that increases the consumption.
특히, PET와 같은 합성수지가 수지 공급로뿐 아니라 밸브핀이 작동하는 구간 중 밸브핀과 핀가이드부쉬 사이의 미세한 틈새에 퇴적되면서 피스톤의 동작 효율을 저하시켜 게이트의 실링과정의 정밀도를 하락시키면서 제품 생산의 계획에 대한 차질이 발생하여 경제적 손실을 유발시키는 문제점이 있다.In particular, synthetic resins such as PET are deposited in minute gaps between the valve pins and the pin guide bushes during the operation of the valve pins as well as the resin supply path, reducing the operation efficiency of the piston and reducing the precision of the gate sealing process. There is a problem that causes economic losses due to the disruption of the plan.
